The Geological Survey of Western Australia (GSWA) is a division within the Department of Mines and Petroleum (DMP) that publishes reports, maps, and state-of-the-art databases documenting the geology of Western Australia.

This information provides the building blocks for the design of resource exploration programs in Western Australia. It is also critical in Government decision making, particularly on economic and land use issues. Since the 1880s GSWA has been gathering, synthesizing, and publishing information on the State's geology, and mineral and petroleum resources.

Access reports, maps, and GIS information on the geological and resource potential of Western Australia's large sedimentary basins. Both onshore and offshore exploration information can be downloaded free from the WAPIMS database.

GSWA has an extensive catalogue of information about geology and related areas including geotourism, earth science, mapping, and geological time and its processes. Information found here is useful for students of all ages interested in Western Australian geology.
